Abstract
The invention discloses a multifunctional modular rotating shaft, relates to the field of medical crane rotating shafts, and solves the problems that a conventional rotating shaft is complicated in assembling, high in difficulty and long in time, a limiting piece is complicated and non-economic in design, the overall structure is not compact, and an electromagnetic brake cannot be alternatively assembled. The multifunctional modular rotating shaft comprises an outer rotating shaft ring and an inner rotating shaft ring, wherein the outer rotating shaft ring is of an overall forged structure with a flange; the inner rotating shaft ring is of an overall forged structure with a flange; connection holes are formed in the top surface of the flange of the outer rotating shaft ring; limiting indexing holes, limiting blocks and a mechanical braking acting surface are arranged on the outer rotating shaft ring; mechanical braking holes, braking component clamping slots and limiting columns are arranged on the inner rotating shaft ring. By the adoption of an embedding method for arranging the limiting blocks and the limiting columns, the overall structure is compact, the whole size and the weight of the rotating shaft are reduced, the design is modularized, the rotating shaft assembling time is shortened, and an air bag brake and the electromagnetic brake can be alternatively assembled. The multifunctional modular rotating shaft is suitable for the field of medical instruments.
